FOSSY 2026: What’s a Data Lake and What Does It Mean For My Open Source Stack?
Data lakes on open table formats like Iceberg are a popular way to manage large datasets for analytics, data science, and AI. This talk explains how data lakes work and how to adapt open source analytic stacks to use them. First, we'll tour projects like Arrow, Iceberg, and Unity Catalog that make data lakes possible. Next, we'll see how analytic engines like DuckDB, ClickHouse®, and Spark are adapting.
Finally, we'll survey a few projects that enable applications written in Python, Golang, or Rust to deliver fast queries. You'll have to build the app yourself, but this talk will show you a path to use data lakes and open source successfully.
FOSSY 2026 – O11y in One: Exploring ClickHouse® as a Unified Telemetry Database
OpenTelemetry unified how we collect telemetry, but most teams still juggle a handful of monitoring backends. Could ClickHouse® be the single datastore that brings them together?
Josh explores what makes ClickHouse a strong fit for traces and logs, how it integrates with OpenTelemetry, Prometheus, Grafana, and Kafka, and the open-source observability platforms built on it, including CoRoot, QRYN, and SigNoz.
